WATER-CLOSET.

Specification of Letters Patent.

Patented Dec. 8, 1914.-

Application iled September 8, 1913. Serial No. 788,512.

'This invention relates to 'water closets' and consists of certain novel arrangements of high pressure water supplies which are delivered into the outlet pipe of the bowl to force the contents of the bowl outward by suctionand as an overflow to fall into the bowl from its upper rim, the latter supply being discharged from a muiller into a pocket at one side of the bowl and carried to the-overflow gutter in the rim through side passages, the object of .the invention being to supply the clearing water without the usual noises which are so objectionable in the forni of bowl now in use, as will be more fully described in the following specificati0n, set forth in the claims and illustrated in the accompanying drawings, wherein:

Figure 1. is a longitudinal sectional view of the improved bowl and the supply valve. Fig. 2. is a cross sectional view of the bowl. Fig. 3. is a detail view of the Inuiler.

- In the flushing of water closet bowls it is usual to supply the necessary pressure to the water by means of tanks located at various elevations to afford suiiicient fall to the water to carry oi the heavy foul Water and this sudden rush of water results in noises 'of greater or less degree, and it is to overcome these objectionable features that the present invention is designed.

The bowl 5 as shown in the drawings is similarv in'shape to the ordinary bowl and has its outlet 6 at the front end and which is a Siphon with one end terminating at the bottomgof the bowl while the other end connects with the pipe 7 leading to the sewer. The upper rim 8 of the bowl is hollow and on the .inside of the bowl is provided with aplot 9 of less width than the inside diameter of the hollow rim so Aas to leave a gut-V ter 10 around the entire interior of the bowl.

At one side of the bowl, and preferably the rear side, is a chamber 11 communicating by means of the two side passages 12 with the hollow rim and the gutter 10, and fitted within this chamber is the muliler 13 consisting of a metal cup with staggered slots 14,

arotuid its sides and through which the i water issues to fill and overflow the gutter 10 when the balance of the flushing water is supplied to a passage 15 termina-ting in a nozzle 16 to issue into the 4inner-end of the siphon and force the contents of the bowl out of the pipe 7.

The water supply may be from arrordv nary pressure or high pressure main and when divided for the above described discharges will be found abundant to properly flush and cleanse the *tank and this supply is furnished through theinlet pipe 17- into the valve chamber 18, and is released by the valve 19 when pressure is applied to the knob 20. The spring 21 is sufliciently strong to resist the pressure of the water, but when the water passes the valve it is vdivided, one partpassing to the muliler 13 through the pipe 22 vwhile the other portion passes through the trap 23 and into the pipe Hand the passage 15. The supply of water to the nozzle 16 and the gutter 10 is regulated by. the valves 25 and 26, so'that the pressure may be reduced at eachv of the outlets. It will therefore be seen that any sound following the issue of water from the nozzle is drowned in the outgoing water and any hissing or splashing of the discharge is so far in the siphonthat it will not be heard on the outside. The water passing from the mutller will be noiseless and the overflow from the gutter -simply drips into the bowl to bel carried otl' by the nozzle 16.

The constructionuof the bowl is very simple and no resistance is offered to theA outward movement of the water while the overllow is simple and noiseless.

The metallic connections may be by means 'of screws and are accessible while the regulation of the water supplies may be instantly performed.'

It is obvious that'the details may be modified and the parts otherwise arranged with-I at the bottom of the bow of a muler inV loo the muffler chamber, water supply pipes for the muflier and the inlet nozzle, and a valve controlling the supply pipes.

2. In water closets, the combination with a bowl having a muller chamber, a slotted hollow rim communicating by means of trapped passages with the muier chamber and a passage terminating in an outlet nozzle in the bottom of the bowl, of a trap for the latter, supply pipes for the trap and the muiller chamber, and a. valve controlling the same.

3. In water closets, the combination with a bowl having a hollow slotted rim and a. muier chamber connected with each other muiller and the discharge pipe with water. l Signed at New York in the county of New by means of trapped passages, of a dis-f charge pipe with a nozzle terminating in the outlet of the bowl, a trap in the discharge pipe, a muier in the chamber, and a pipe controlled by a valve supplying the York and vState of New York this 20th day of August A. D. 1913.
